Description
Die Erfindung betrifft eine Vorrichtung mit einer Reinigungseinheit zur Bereitstellung einer Schmelze, etwa um diese in einer Kunststoffverarbeitungsmaschine oder dergleichen weiterverarbeiten zu können, nach dem Oberbegriff des Anspruchs 1.The The invention relates to a device with a cleaning unit to provide a melt, such as in a plastic processing machine or the like to further process, according to the preamble of claim 1.
Derartige Vorrichtungen dienen dazu, beispielsweise in Extrudern verwendete Kunststoffschmelzen mechanisch von Verunreinigungen zu befreien, um sie dann weiterverarbeiten zu können. Hierfür weist eine solche Vorrichtung etwa eine Reinigungseinheit mit einer metallischen Siebscheibe auf, die mit mehreren Siebeinsätzen, die über den Umfang aufeinander folgen, versehen ist. Die Siebeinsätze werden nach einer gewissen Funktionszeit einer Eigenreinigung ausgesetzt, um Verschmutzungen, welche die Lochkanäle zusetzen, zu entfernen. Ohne die Reinigung würde schnell ein erheblicher Gegendruck durch zugesetzte Siebbereiche entstehen, der die reinigende Funktion der Siebe für die Schmelze stören würde.such Devices serve, for example, used in extruders Mechanically free plastic melts from impurities, to then be able to process them further. For this purpose, such a device about a cleaning unit with a metallic screen disc on those with several sieve inserts, the above the circumference follow one another, is provided. The sieve inserts will be exposed to self-cleaning after a certain period of operation, to remove soiling, which can clog the hole channels. Without the cleaning would quickly a significant back pressure due to added sieve areas emerge, the purifying function of the sieves for the melt to disturb would.
Aus der WO 01/43 847 ist bekannt, zur Eigenreinigung die Siebeinsätze mit einem Reinigungsstrom zu beaufschlagen, welcher der Durchtrittsrichtung des Schmelzestroms durch die Siebscheiben entgegengesetzt ist. Dieser Gegenstrom wird in einem von dem Hauptschmelzekanal abgezweigten Rückspülkanal erzeugt. Um in Abhängigkeit vom Verschmutzungsgrad die Eigenreinigung der Siebeinsätze zu optimieren, wird dort eine Steuervorrichtung vorgeschlagen, die das Schmelzevolumen und/oder die Fließgeschwindigkeit der rückspülenden Schmelze bestimmt und deren Eingangsgrößen von während des Betriebes ermittelten Prozesspara metern gebildet sind. Eine derartige Vorrichtung kann jedoch auf wechselnde Qualität der zugeführten Komponenten nur mit angepasster Reinigungsleistung der Siebeinsätze reagieren, so dass unter Umständen, etwa bei verklumptem Ruß, der zugeführt wird, zwar die Siebeinsätze ihre Funktion erfüllen, jedoch die Ausgangszusammensetzung der Schmelze nicht den gewünschten Anforderungen entspricht.Out WO 01/43 847 is known, for self-cleaning with the sieve inserts to act on a cleaning stream, which the passage direction the melt flow through the screen discs is opposite. This Counterflow is diverted in one of the main melt channel Backwash channel generated. In order depending on Pollution degree to optimize the self-cleaning of the sieve inserts, There is proposed a control device which determines the melt volume and / or the flow rate the backwashing melt determined and their input variables of while formed by the operation process parameters are formed. A However, such device may be for changing quality of the supplied components react only with adapted cleaning performance of the sieve inserts, so that under circumstances, for example with clumped soot, which is supplied although the sieve inserts fulfill their function, however, the starting composition of the melt would not be the desired one Meets requirements.

Hinsichtlich vorteilhafter Ausgestaltungen wird auf die weiteren Ansprüche 3 bis 6 verwiesen.The Invention solves this object by a device with the features of the claim 1 and by a device having the features of claim 2, which can be realized individually or in combination with each other. Regarding advantageous embodiments is based on the further claims 3 to 6 referenced.
Erfindungsgemäß ist in der Ausbildung nach Anspruch 1 die Möglichkeit eröffnet, aufgrund gemessener Parameter und ggf. daraus ermittelter filterspezifischer Prozeßdaten mit einer Änderung der zugeführten Prozeßmaterialien und/oder Prozeßrnaterialienzusammensetzung und/oder deren Verarbeitungsparameter reagieren zu können und somit eine gleichmäßige Qualität des Produkts auf der Ausgangsseite sicherzustellen.According to the invention is in the training according to claim 1 opens up the possibility due measured parameter and possibly determined therefrom filter specific process data with a change the supplied process materials and / or process material composition and / or their processing parameters to be able to react and thus a uniform quality of the product on the exit side.
In der Ausbildung nach Anspruch 2 kann andererseits auch bei nicht völlig gleichbleibenden Produkteigenschaften die Weiterverarbeitung angepaßt werden, etwa dadurch, dass in der Vorrichtung oder einer nachgeschalteten Weiterverarbeitungseinheit bei größer werdender Viskosität der Schmelze flexible Rohrquerschnitte erweitert oder Ventilöffnungszeiten verlängert werden, um die Fließgeschwindigkeit der dann zäher werdenden Schmelze und somit die Prozessführung konstant halten zu können.In The training of claim 2, on the other hand, not at completely constant product properties are adapted to further processing, approximately in that in the device or a downstream Further processing unit with increasing viscosity of the melt flexible pipe cross-sections can be extended or valve opening times extended, around the flow rate of then tougher expectant melt and thus to be able to keep the process control constant.
Besonders vorteilhaft beeinflußt die Regelung aufgrund der von der Sensoreinheit ermittelten Daten die Arbeit der Reinigungseinheit und die Regelung der Zusammensetzung der zugeführten Komponenten in wechselseitiger Abhängigkeit. Damit ist es beispielsweise möglich, wenn die Sensoreinheit einen zu geringen Rußanteil – und somit eine zu geringe Schwarzfärbung – in der Schmelze detektiert, sowohl die Eigenreinigung des Siebfilters zu erhöhen, weil Verklumpungen auf der Filtereingangsseite vorliegen können, als auch bei den zugeführten Komponenten den Rußanteil zu erhöhen, weil offensichtlich eine zu große Rußmenge im Siebfilter hängenbleibt und somit für das Produkt nicht zur Verfügung steht. Somit kann auch unterschiedlichen Qualitäten der zugefügten Komponenten Rechnung getragen werden.Especially favorably influenced the regulation based on the data determined by the sensor unit the work of the cleaning unit and the regulation of the composition the supplied Components in mutual dependence. That's it, for example possible, if the sensor unit too low soot - and thus too low Black coloring - in the Melt detected, both the self-cleaning of the mesh filter to raise, because Clumping on the filter input side may be present as also with the supplied Components the soot content to increase, because obviously too big soot gets stuck in the strainer and thus for the product is not available stands. Thus, also different qualities of the added components Be taken into account.

Insgesamt kann damit der Prozess sich erstmals als Ganzes – und nicht nur die Parameter der Filtereinheit – selbst vollautomatisch regeln. Ein manueller Eingriff ist dabei nicht mehr erforderlich.All in all This allows the process to be considered as a whole for the first time - and not just the parameters the filter unit - itself fully automatic control. A manual intervention is not more required.
Der Vorteil liegt darin, daß man den Filter immer maximal nutzen kann, in dem die Dosierung der zuzuführenden Komponenten als auch die Verfahrensparameter automatisch optimal angepasst werden.Of the Advantage is that one the filter can always maximize use, in which the dosage of the supplied Components as well as the process parameters automatically optimally be adjusted.

Die Erfassung all dieser wesentlichen Daten stellt die konsequente Weiterverwertung der Prozessdaten dar, die sich aus dem filterspezifischen Kontrollsystem ergeben und die nunmehr zusätzlich eine umfassende und vor allem vollautomatische Prozeßsteuerung des gesamten Produktionsprozesses ermöglichen.The Capturing all this essential data represents the consistent re-use the process data resulting from the filter-specific control system result and the now additionally one comprehensive and above all fully automatic process control of the entire production process enable.
Voraussetzung für eine solch komplexe Steuerung ist ein Filter, wie er z.B. durch die WO 01/43 847 zum Stand der Technik gehört, bei dem das Schmutzkuchenprofil im Schmelzkanal zeitlich konstant ist und der Filter somit ein nahezu analoges Signal für die benötigte Filterfläche pro Zeiteinheit liefert.requirement for one such complex control is a filter such as e.g. by WO 01/43 847 belongs to the state of the art, in which the dirt cake profile in the melt channel temporally constant is and the filter thus a nearly analog signal for the required filter area per Time unit supplies.
Bei anderen Filtriersystemen kann man dies auch rein theoretisch aus dem Druckanstieg pro Zeiteinheit ableiten, dieser ist jedoch nicht linear mit der Schmutzmenge verknüpfbar, so daß eine solche Berechnung theoretisch sehr kompliziert, und daher in der Praxis nicht umsetzbar ist. Bei Rückspülfitern ist dies zudem überhaupt nicht umsetzbar, da die rückgespülten Siebe immer einen undefinierten und auch nicht kontrollierbaren Zustand haben.at This can also be done theoretically from other filtration systems Derive the pressure increase per unit time, this is not linearly linked to the amount of dirt, so that such Calculation theoretically very complicated, and therefore in practice is not feasible. For backwashers is this anyway not feasible, since the backwashed sieves always an undefined and uncontrollable state to have.
